UniProtKB description: Cell wall-anchored surface receptor that extracts heme from oxidized metHb to enable growth on hemoglobin as a sole iron source. Rapidly extracts heme from hemoglobin and transfers it to IsdA or IsdC, which then relays it to the membrane transporter/IsdEF for internalization. Promotes also resistance to hydrogen peroxide and killing by neutrophils.
